The first generation of Heavenly Demon, Tianlong, was the first warrior in history. He once swept across the Central Plains with the realm of gods, but was sealed in ten thousand years of ice by his old enemy, the White Dragon Sword God Bai Yunhui, using the Demon Sealing Sword Formation. After two hundred and five years of slumber, the seal was accidentally lifted, and the Lord of Demons returned to the world.
After waking up, Tianlong found that the demon sect had been destroyed long ago, and his loyal subordinates had turned into dust, leaving only blood descendants and a tampered history. Starting from Beihai City, he single-handedly crushed the Northern Sword Sect, broke through the Beihai Ice Palace, and retrieved his beloved sword, the Heavenly Lord Demonic Dragon Sword. In Qionglu Mountain, Liaodong, he found the descendants of Liang Wuliang, the "Loyal Ghost Sword" in his right arm - Ghost Sword Villa, which was being oppressed by the Fine Sword Sect and was on the verge of destruction. In order to make up for the guilt of his old troops, Tianlong regained his strength while revitalizing the villa, preparing to conquer the Central Plains again.
This is a story about loyalty and waiting, as well as a legend about the return of a generation of demons.
